无创血压测量示波法分析与研究

The investigation of non-invasive blood pressure measurement using oscillometric method

本文简要介绍了目前血压的测量方法,主要讲述了比较流行的无创血压测量方法示波法。在分析基于日立HD64180微处理器的无创血压测量模块基础上得出示波法的血压测量过程。在保持现有示波法的基础上,充分利用医疗仪器方面的最新硬件技术,设计出了上下位机测量系统,在测量算法与工程实现方面做了一些有益的探索。

This paper briefly introduces the measurement of blood pressure,non-invasive blood pressure measurement using oscillometric method is mainly demonstrated.Then based on analysing hardware circuit and source code of non-invasive blood pressure measurement module,whice takes advantage of Oscillometric method Hitachi HD64180 microprocessor,the way to determine blood pressure is obtained.Maintaining many current advantage,some beneficial exploration,for example designing upper and lower computer measurement system,have been made in algorithm and engineering using the latest hardware technology in medical equipment filed.
